Bouvier's Law Dictionary, Revised 6th Ed (1856)
QUASI TRADITION, civil law. A term used to designate that a person is in the
use of the property of another, which the latter suffers and does not
oppose. Lec. Elein. Sec. 396. It also signifies the act by which the right
of property is ceded in a thing to a person who is in possession of it; as,
if I loan a boat to Paul, and deliver it to him, and afterwards I sell him
the boat, it is not requisite that he should deliver the boat to me, to be
again delivered to him there is a quasi tradition or delivery.
